Document Metadata Subscription
Summary
This profile describes the use of subscription and notification mechanism for use within an XDS Affinity Domain and across communities. The subscription allows for the matching of metadata during the publication of a new document for a given patient, and results in the delivery of a notification. This profile is based on the OASIS WS-BaseNotification standard and, in accordance to that, defines two methods of subscription and notification:
a) In the “Push-style”method, a Document Metadata Subscriber may subscribe on behalf of the Document Metadata Notification Recipient to receive notifications about the availability of documents based on specific criteria. A Document Metadata Notification Broker keeps track of the subscriptions and sends the appropriate notifications based on the registration of objects in an XDS Document Registry. Subscriptions exist for a certain period of time and can be cancelled.
b) In the “Pull-style” method, a Notification Puller actor creates a Pull Point resource able to store notification generated by the Document Metadata Notification Broker actor. This Pull Point resource is a resource managed by the Pull Point actor that allows the storing of notification targeted to a specific recipient.Notifications stored in the Pull Point actor can be retrieved by the Notification Puller actor using a specific transaction
Benefits
